What Is Cyber Security?

The cyber security field covers a wide range of practices and technologies designed to prevent, detect and respond to cybersecurity attacks. Cybersecurity includes strategies like securing systems, protecting data and educating employees. It also involves policies, procedures and technology like firewalls, antimalware software and encryption.

While all computer systems are at some level of risk from cyberattacks, larger entities like businesses and government systems are more likely to be targeted. This is because they typically hold a deluge of sensitive and confidential information.

Despite the best cybersecurity protocols, human error can make or break an organization’s defenses. This is why it’s important to reinforce basic cybersecurity principles with employees outside of the IT department. It’s also why frequent, periodic data backups are so valuable. Backups provide a snapshot of a system’s previous state and can help mitigate the effects of a breach or other type of attack.

The cyber threat landscape is constantly evolving. As new technologies emerge and attacks become more sophisticated, it can be difficult to keep up. To address this challenge, cybersecurity practitioners must use outcome-driven metrics to enable more effective governance over priorities and investments in security controls. MDR
